Dyna-Plex 21C Bar and Chain Oil

Dyna-Plex 21C Bar and Chain Oil

Heavy-Duty Off-Road, Industrial

Dyna-Plex 21C Bar and Chain Oil ISO 68 is a high-quality bar and chain oil that is a carefully balanced blend, which achieves optimum all-weather lubrication. A special additive has been added to provide tackiness to prevent “throw-off” from rapidly turning and vibrating bar and chain mechanisms. In addition, it is fortified with an excellent water displacing anti-rust additive.

Dyna-Plex 21C Alcor 628 Heat Transfer Oil

Dyna-Plex 21C Alcor 628 Heat Transfer Oil

Heavy-Duty Off-Road, Industrial

Dyna-Plex 21C Alcor 628 Heat Transfer Oils are specially refined non-corrosive, non-toxic, odorless heat transfer oils, which provide superior heat absorption and exhibit outstanding thermal stability and oxidation resistance at constant high operating temperatures. Formulated from selected petroleum stock and additives, these oils provide reduced oxidation essential for even distribution and rapid heating, making them ideal for low atmospheric temperature work.

  • Noncorrosive to steel, stainless steel, iron, aluminum and copper systems
  • Recommended for all fluid heat transfer systems, both open and closed
  • Superior thermal stability resists deterioration and cracking, even in systems with fluid temperatures above 500 F
